C***DESCRIPTION
C
C   DVI1 computes the modified (hyperbolic) Bessel function of the
C   first kind of order one (I1) for real arguments using uniform
C   approximation by Chebyshev polynomials.
C
C
C   P A R A M E T E R S
C
C   M      (Input) Integer
C          The number of arguments at which the function is to be
C          evaluated.
C
C   X      (Input) Double precision array of length M
C          The arguments at which the function is to be evaluated are
C          stored in X(1) to X(M) in any order.
C
C   F      (Output) Double precision array of length M
C          F(i) contains the value of the function at X(i), i=1,..,M.
C
C   WORK   (Work) Double precision vector of length 7*M
C
C   IWORK  (Work) Integer vector of length M
C
C   INFO   (Output) Integer
C          Indicates status of computed result. The following table
C          lists possible values and their meanings.  If OK=Yes then
C          all F(i) have been set, otherwise none have been set.
C
C          INFO  OK            Description
C          ------------------------------------------------------------
C           -1   Yes  Warning: Some abs(X(i)) so small I1 underflows.
C                     The corresponding F(i) are set to zero.
C            0   Yes  Successfull execution.
C            1   No   Error: M .LE. 0
C            2   No   Error: Some abs(X(i)) so big I1 overflows.
C                     The index of the first offending argument is
C                     returned in IWORK(1).
